ALBANY — An online invitation to a city apartment resulted in an assault with injures and three arrests, police said Thursday.

Police said a Queensbury man, 32, met a woman through the online advertising service "Backpage," but when he got to the apartment at the 200 block of State Street on Tuesday afternoon he found out the woman was really a man and he tried to leave.

Instead, three men blocked him from leaving and tried to steal his money, police said. He tried to escape through a second-floor window but two suspects shoved him and he fell 21 feet to the ground, injuring his legs and ankles, police said.
